The Seekins Precision NOXs handguard was developed in response to the huge outcry by consumers that bulky, outdated picatinny rails where heavy and clunky. Well Seekins Precision decided to answer the call! Engineered to provide you with a lightweight, ultra-thin attractive looking handguard the NOXs has several features that other handguards just can't compete with. The NOXs features an anti-rotation QD sling attachment point milled directly into the handguard. Cooling slots have been added to provide you with maximum airflow preventing the barrel from overheating during sustained periods of shooting. In included proprietary barrel nut features a Cross-lok mounting system which ensures that the anti-rotation comes from both the steel barrel nut and the NOXs handguard making this a rock solid un twist able connection.
